Color Space

RGB = Red, Green, BlueCMYK = Cyan, Magenta, Yellow, Black

All files in the RGB color space must be converted to CMYK color before printing. The conversion process can cause color shifts in RGB colors not capable of being reproduced in the CMYK color space. We suggest you convert all graphics and colors to CMYK before creating your PDF files,
so that the colors that you see on the screen most closely match the
final printed product. If RGB files are submitted they will be automatically converted using the "GRACoL2006_Coated1v4" ICC profile, and colors in
your printed product may vary slightly from the expected.Spot Color
Colors created without screens or dots, such as those found in the
Pantone Matching System®, are referred to in the industry as
spot or solid colors. From a palette of 14 basic mixing colors,
each of the spot colors in the Pantone Matching System is
mixed according to its own unique ink mixing formula
developed by Pantone. You probably mixed yellow and blue
paint to get green in your youth. Creating a Pantone pot
color is similar in concept, but with the added need for
precision. Spot Color is typically not possible with digital printing, because the toners and inks are not available in spot colors. All spot colors must be converted to CMYK before printing on a digital press. Some converted spot colors match very close to solid ink, while others change considerably. Please refer to a Pantone® Color Bridge™ guide which displays each
Pantone Color and its corresponding simulation
in CMYK, before selecting a color.
